Re: Hesitant on acceleration and nothing when you mash the throttle
Batteries last longer in cold weather states. I use a battery tender, but sometimes they fail or become marginal. I?ll be hunting down a new battery when it is safe for me to shop in public.

Re: Hesitant on acceleration and nothing when you mash the throttle
In general I get about 3 years on batteries down here, the heat is a killer. This year I have insulating blankets on two of them, not sure if that will really matter much. On the vehicles I use a tender on it stretches a little. I just went to AGM on two other cars, I hope they last a bit longer.

Re: Hesitant on acceleration and nothing when you mash the throttle
Ok fuel pressure at idle is at 21psi...I know it should be around 43 at idle....Did not drive it yet with gauge Attatched....Lots of snow and ice...
Guess the next thing is check the draw on each pump with a multi meter ? Let me know...Thnx for all the help.. |

Re: Hesitant on acceleration and nothing when you mash the throttle
Dude, the pump/pumps are done. 21 PSI warm, cold, hot, any reason pump/s = B A D.

I?d put vacuum on the regulator and see if it holds.

It wasn't the pumps....It was a sensor near the headers.....Thought it was the pumps... Will try checking the current with the meter...Pulled hose off regulator and its dry...No fuel leaking if that helps... |
